What is an XLSX file?

An XLSX file is a file format used for spreadsheet applications. It is an updated version of the XLS file format used in Microsoft Excel 2003 and earlier versions.

How does an XLSX file work?

An XLSX file is a collection of cells organized into rows and columns. Each cell can contain text, numbers, or formulas that perform calculations based on the data in other cells.

The XLSX file format consists of several XML files that are zipped together into a single file. These XML files contain the data, formatting, and metadata for the spreadsheet. When you open an XLSX file, your spreadsheet application extracts the XML files and displays the data in a user-friendly format.
